Western Automation supplies metering products for monitoring building energy consumption, including Kamstrup MULTICAL thermal energy meters and associated equipment.
Applications include heating, cooling, energy monitoring and integration into BMS systems.
Control pumps, fans and air-handling equipment with dedicated HVAC drives including:
ABB ACH580
Danfoss VLT HVAC Drive FC 102
Schneider Electric Altivar HVAC drives
Need help selecting a drive?
Send us the motor kW, supply voltage, current and application and our team can assist with selection.
Our wider building-controls range includes energy monitoring, metering, gateways and integration products designed to help BMS engineers connect, monitor and optimise building systems.
Instead of sourcing sensors from one supplier, actuators from another and drives from somewhere else, send Western Automation the complete controls schedule.
We'll help source the requirement across our building-controls supplier portfolio.
Western Automation combines specialist building-controls knowledge with the product range of a major electrical and automation distributor.
That means one enquiry can cover BMS sensors, valves, actuators, HVAC drives, energy meters, electrical control products and panel components.
